AbstractReviewed are the recent laser fusion research activities of ILE, Osaka University. The issues which are discussed here are: (i) the present status of the GEKKO XII laser system; (ii) recent achievements on implosion hydrodynamics; (iii) implosion stability and symmetry in GEKKO XII experiments; and (iv) fundamental research related to fast ignitors. One of the important recent achievements is the finding of reduction of the Rayleigh–Taylor growth rate due to the non-local heat transport in directly-driven ablation plasmas. Another significant progress is the observation and analysis of the intense laser channeling in over-dense plasmas. Those two achievements are described in detail.
大阪大学ILE最近的激光聚变研究活动综述。本文讨论的问题包括：(i) GEKKO XII激光系统的现状；(ii) 内爆流体力学的最新成果；(iii) GEKKO XII实验中内爆的稳定性与对称性；以及(iv) 与快点火相关的基础研究。近期重要成果之一是在直接驱动烧蚀等离子体中发现了非局域热输运对瑞利-泰勒增长率的降低作用。另一项重大进展是对过稠密等离子体中强激光通道化的观测与分析。这两项成果将进行详细描述。
